6.1 Power supply: Panel meter working voltage range AC/DC 85~265V To prevent damage to the instrument, it is recommended when using AC power, add 1A fuse on the phase line; In areas with poor power quality, install a surge suppressor in the power supply circuit is recommended.
6.2 Power signal input (current and voltage input): Current input for A, B, C three-phase alternating current signal input, which I * for Current input terminal; For A, B, C three-phase AC voltage input voltage signal input terminal. When wiring, please ensure that the input signal phase sequence and polarity. The input voltage should not higher than rated input voltage, or consider using PT, the voltage input required to install 1 A fuse. Rated input current should not higher than rated input current, or external CT should be considered.
6.3 Electrical pulse output: P+ Q+ for active/reactive power pulse output +, P- Q- for active/reactive power output pulse output - . Electricity pulse output corresponding to the secondary data, calculating electricity should multiply voltage transformer ratio and Current transformer ratio.
6.4 Rs485 Communication Wiring
Panel offer a Rs485 Communication interface, MODBUS_RTU, by one road Max capacity is
32 set, All the panel meter has own unique Meter ID. Connection wire should be used Copper
wire is shielded twisted-pair cable, wire diameter not less than 0.5 mm. Avoid high voltage cable or other strong electric field environment, the maximum transmission distance is 1200m,
